Unravelling the mysteries of the universe: it’s a big task. And that’s one of the reasons that experts come to CERN – to test themselves, push their abilities and help create history with groundbreaking discoveries. But this is not just about physics. The engineering and technical skills needed to make the experiments succeed are as world-class as the science behind them. If you want to help answer the world’s toughest questions, this is the place to do it.
